Any update to the SRNG TP/HP when the device is in low power
state would result in system errors. It is recommended to disable
EXT grp irqs and drain TXRX before sending power save enter command
to the FW. This will ensure that no interrupts are received while
in power save mode and as a result there wont be any HP/TP updates.

In Moselle, currently CE interrupts are not disabled from apps
side during ipci bus suspend, so adding changes to disable all
the CE interrupts except wake_irq during bus suspend and do the
symmetric inverse operation during bus resume, also drain all
the pending FW diag logs from copy engine.

Issue1: Driver RTPM state is ON/NONE, Kernel state is RESUMING.
cdp_runtime_resume is already complete,
hif_pm_runtime_get return -E_INPROGRESS,
dp_tx_hw_enqueue will set the flush event,
but cdp_runtime_resume is already done,
this flush event will be handled only on next pkt tx.
Issue2: Driver RTPM state: Resuming
hif_pm_runtime_get returns -EBUSY,
dp_tx_hw_enqueue is interrupted by any IRQ,
cdp_runtime_resume is completed,
dp_tx_hw_enqueue will set the flush event,
This flush event will be handled only on next pkt tx.
Fix:
Introduce a link_state_up atomic variable in hif to track the link state
change by pld_cb.
Set atomic variable link_state_up=1 in pmo_core_psoc_bus_runtime_resume
just after pld_cb. pld_cb brings the PCIe bus out of suspend state.
Set atomic variable link_state_up=0 in pmo_core_psoc_bus_runtime_suspend
just before pld_cb. pld_cb puts the PCIe bus into suspend state.
Introduce dp_runtime_get and dp_runtime_put.
dp_runtime_get get refcount with increment of an atomic variable.
dp_runtime_put return refcount with decrement of this atomic variable.
If hif_pm_runtime_get returns -EBUSY or -EINPROGRESS,
take the dp runtime refcount using dp_runtime_get,
check if the link state is up, write TX ring HP,
return the dp runtime refcount using dp_runtime_put.
cdp_runtime_suspend should reject the suspend, if dp_runtime_get is non
zero.
cdp_runtime_resume should wait until dp_runtime_get becomes zero or time
out, then flush pending tx for runtime suspend.

Currently if the driver is in runtime suspend/suspending
state, any packet transmission will request for resume
via hif_pm_runtime_get.
Unfortunately there is a logging in the above API which
will lead to more time consumption in the NET_TX softirq
context. This can lead to other delay in processing other
softirqs in the system.
Fix this by skipping the logging in the packet transmission
path.

Currently DMA mask for the device is set during hif_enable_bus.
If the datapath memory prealloc feature is enabled, there are
a few dma memory allocation which is done before the DMA mask
is set for the device. This leads to the aforementioned dma
memory pre-allocation to be attempted at the default DMA mask.
Due to this the entire device capability of dma address might
not be used.
Add hif api to set dma mask before hif is initialized. This
is needed to set dma mask in case of datapath memory pre allocation.

UMAC reo full condition is seen in slub debug builds in case of
DL throughput traffic. This is due to host process only 64 packets
per NAPI schedule in case of slub debug builds where in case of
perf builds budget is of scale 4 times. Also the time between two
napi schedules is in order of milliseconds which accounts for the
delay of host reo ring processing. So increase the napi budget
scale to 3 times which make sures host process enough packets per
napi schedule.

Add runtime pm apis to record last busy mark set by data path
during dp rx process.
Currently for mcl in some scenerios runtime sync suspend is issued
which puts the link in low power state with out waiting for link
inactivity timeout. This leads to throughput degradation in case of
rx direction as in rx processing data path extends the timer by marking
last busy to avoid immediate runtime suspend. But runtime sync suspend
does not take in to account of the link idle timeout value before
suspending the link. So using this apis, before issuing runtime sync
suspend check the duration since last busy mark by data path rx process.
If the duration is less than run time delay just do runtime put.
